Chapter 1626

At this time, the zombies group had filled the Nanshu base, and even the material warehouse in the center was inevitable. People who did not face these zombies at a high altitude were in a complex mood because they stood high and looked far away. They could have a panoramic view of the Nanbu base, and could have a deeper understanding of the current situation.

He Feng and others are looking at Chu Han nervously. The corpse tide has arrived at the most difficult moment to fight against. What cards can Chu Han turn over?

Bang!

A little noise.

Chu Han's finger directly pushed the big stereo switch, and the tiny sound also made people in the room look away, looking at the big guy who was invented by young master Chen and specially sent to the front line of the battlefield.

With this thing alone, they can turn the tables?

Many people began to doubt from the bottom of their hearts, let alone Gao Shaohui, who thought it was useless from the beginning to the end. Chu Han also just got this thing in his hand. No one knows how the effect is.

Only when Chu Han pressed the open button, a very subtle sound wave came from the sound, and transmitted the sound wave to every corner of the base through the loudspeaker in the command room.

After the sound was infinitely amplified, many people also heard it. It was just a very strange thing. The sound was very loud, but they didn't hear it really.

It's a bit like the cry of a dolphin, but also a little like the cry of a baby. It's very strange!

Several people in the command room looked puzzled. They didn't understand how this strange voice would help them in this battle?

"Can you hear me clearly, but I can't hear you clearly?" Chu Han was laughing.

He Feng nods to answer: "intermittently."

"How do I hear a melody?" At this time, Gao Shaohui was surprised: "it is not intermittent, but continuous, super ugly melody!"

"I wish I were different from you." "I only hear a scream every once in a while," another member of the staff said with a frightful expression

All of a sudden, the people in the room looked at each other, their faces were ugly, and everyone heard different voices. Could it be the ghost?

Chu Han was not surprised: "it's normal that ordinary people can hear a sound frequency between 20 Hz and 20000 Hz, while the range of new humans will expand, and with the increase of the order, the range will be wider. Gao Shaohui has a natural advantage. He can hear a lot of frequencies than our range, so he can hear all the sounds at present."

Listening to Chu Han's explanation, everyone understood, but there was still a key problem that did not understand.

Jiang Tianqing immediately asked: "I didn't understand any Hertz frequency. I just want to know what's the relationship between this and corpse tide?"

Chu Han's eyes were like a torch: "you should know that zombies generally have no vision, but their hearing is extremely keen?"

As soon as this was said, the commanding room suddenly became extremely quiet. Intelligent people had already drawn a conclusion from known clues. For example, he Feng was impatient to look out, while those who did not want to understand, such as Gao Shaohui, were still holding his head and staring at Chu Han.

Zombies can hear the sound frequency range, obviously has certain difference with the human!

"My God At this time, a member of the staff yelled, excited and excited: "he Shang is really a genius! Look out there

Almost all the members of the staff headquarters were extremely clever, so they were also the ones who understood it most quickly after he Feng. The rest of the people in the command room unconsciously turned their attention to the battle below after hearing the cry.

At this time, what surprised everyone and surprised Chu Han happened in front of them!

There are more than 7 million zombies crowding the whole Nanshu base, and nearly five million of them seem to be fixed by magic. From the top, it is more obvious that the creeping black spots stay in place like statues.

This sound wave can achieve such an effect!

Although its specific principle is estimated to be only understood by the superior, it does not affect the moment when several people in the command room seize the opportunity.

"All attack! These zombies can't move He Feng immediately ordered in the loudspeaker.

At a time when the five million zombies were unable to move, the members of the wolf tooth battle group, who were almost submerged in the corpse sea, finally emerged.

Although the number of them has decreased significantly, and everyone's clothes have already been scratched by zombies, and many people's skin is full of zombie scratch marks, but in the moment of opportunity, the crazy counterattack of the wolf tooth battle group has begun!

"Kill! Blow up the Zombie's head A small group of recruits grew up and yelled, smashing at the zombie heads that surrounded him.

The rest of the people also re grasp the weapons, killing the surrounding zombies.

No matter how many zombies are unable to move, they are no different from beating ground squirrels, and even save them the time of fighting with them. They just need to lift up the weapons and drop them again and again.In a very short period of time, a large number of zombies swarmed into the base to make trouble fell down in large numbers and spread on the ground, which became the latest carpet of Nanbu base. The roads blocked by the zombies gradually began to have gaps.

He Feng, after giving the order, soon found out the other situation on the scene: "no! These are all low-level zombies, and there are two million zombies over the fifth level. This sound wave only has the strongest effect on low-level zombies below the fifth level. "

"The situation of the three teams on the high wall has not improved, and the fighting is still very fierce." Jiang Tianqing also immediately added: "those are high-level zombies, all more than seven levels."

The five million zombies that can't move are no more than five levels. One million of the remaining two million zombies seem to be struggling with something. They are zombies who have just passed the fifth level or the later stage of the sixth level, wearing and inserting in every corner of the base.

There are the last million, but not too much impact, is still in the crazy attack, it is the three teams facing the group, the level is all over the seventh level!

"Shooting team, attack high-level zombies." He Feng immediately issued the latest order.

In fact, he didn't need to say much. At this time, all members of the shooting team had begun to aim at the zombies. From the perspective of body size and current situation, they could easily distinguish these as attack targets.

"Great! There are only one million and seven zombies left. " Jiang Tianqing was overjoyed, but just finished this sentence, his expression suddenly changed, pale as paper: "more than seven levels of high-level zombies should still have a million?"
